RAILXVAY DUMPING-CAR.

Specification of Letters Patent.

Application filed February 19, 1908. Serial No. 416.693. Renewed March 16. 1909. Serial No. 483.868.

To?! whom it may concern:

Be it known that I. Harmon 1. Hanna, a citizen of the United States, residing at Xorfolk. in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Railway Dumping- Ljars. of which the following is a specific-a tron.

This invention relates to a dumping car and particularly to a construction having a hopper bottom from which the contents are discharged.

The invention has for an object to provide a novel andinun'oved construction of :drum and doors 1]] any desired position.

the discharge door tor the bottom which has its pivot connected to a carrier disposed to move into a casing by which the door is bodily removed from the discharge opening and protected against injury when ing the contents of the car.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined in the appended claims.

In the drawing l igure l is a side elevation of a car having the invention applied thereto; Fig. 2 is a longitudinal section through said car; Fig. 3 is an elevation of the hopper door and carrier therefor; Fig.

discharg- 4 is a detail end view thereof; and Fig. 5 is a detail vertical section through the car casmg.

Like numerals refer to like parts in the several figures of the drawin The numeral 1 designates the longitudinal sills and '2 the cross sills of a car 2" which may be of any desired size or configuration. This car is formed with one or mor hopper portions 3 having fixed inclined bottom portions t disposed toward the center of the car. Cooperating with those portions 1 are oppositely inclined doors or bottoms 5 which when opened permit the material within the car to be freely discharged. The car is provided with a transverse casing or partition 6 into which the doors 5 are adapted to travel when opencittll This casin may be torn'ied with an oppositely inclined upper facet} if so desired to prevent material lodging thereon. Within the casing a carrier or beam 7 is disposed to slide and each of the doors is pivotally connected thereto by any desired means. ()no means for this put-lose comprises the rod 8 carried by the under face of the beam and adapted to rccciw the J shapcd strap hinge i) secured to the door 3 by any means. for instance as shown at it). This carrier may be raised within the ca ing by any prctcrrcd means. for instance, a chain or cable ll connected thereto and passing over pulley 12 disposed within the casing. thence ovcr idler 13 in the opening l-t formed in the car side and downward ovcr idler 15 to the, winding drum it; as shown in Fig. 5. This drum is provided with a hand wheel IT for operating the same and also with a ratchet wheel 18 cooperating with a weighted pawl l9 for holding the For the purpose ot rctaining the doors in closed position when the load is upon them pivoted hooks or fasteners 20 are provided, and this also facilitated by the rod 21 0x tending from the lower portion of the hoppers and adapted to contact with the U- shaped bearing faces 22 on the doors which prevent wear of the door by frictional contact. These rods guide the doors when being raised to discharge the load and when lowered to close the car bottom. and also prevent the doors at any time swinging downward below the bottom and being injured by contact with the track.

in the operation of the invention the car rier is raised through the connections shown and draws the doors and their pivot upward into the casing so that theyarc removed from any obstruction to the discharge of material from the car and also from injury during such operation. The vertical inclination of the doors at the same angle as 3 the fixed bottom of the hopper permits the lar est dischar e o )emn and n'cvcnts the r n n wcdgmg or clogging ot coal or other material when the car is being dumped. The central casing divldcs the load into separate parts also preventing the wcdg ing thereof, and binds the sides of the car together to prevent bulging thus obviating the ,use of tie rods or other obstructing devices c.\'tcnding across the car. it will therefore be seen ,that the invention presents a simple, clli cicnt and economically constructed form of dumping car in which the doors are fully protected both against. injury from contact with the track or the discharge of material fromf the car.

.ll'iiving described my invention and set I forth its merits what I claim and desire to secure by 'Letters Patent is l. The combination with a car having an inclined bottom, of a'casing therein, a pivoted door forming a portion of said bottom, and means for raising the pivot of said door into said casing.

2. The combination with a car having an inclined bottom, of a casing therein, a pivoted door forming a portion of said bottom, and a slidingly mounted carrier within said casing upon which said door is pivoted.

3. The combination with a car having an inclined bottom, of a casing therein, a pivoted door forming a portion of said bottom, a slidingly mounted carrier within said casing upon which said door is pivoted, and means for raising said carrier disposed within said casing.

4. The combination with a car having an inclined bottom, of a *asing therein, a pivoted door forming a portion of said bottom, a sliding-1y mounted carrier within said easing upon which said door is pivoted, and a cable connection from said carrier extending to a winding drum upon said car.

The combination with a car having 21.13;

inclined bottom, of a casing therein, a pivoted door forming a portion ot' said bottom, a slidingly mounted carrier within said casing, upon which said door is pivoted, a cable;

eonnection from said carrier extending, to a winding drum on said car, a ratchet upon said drum, and a pawl mounted to engage said ratchet.

(3. The combination with a car having an inclined bottom, of a casing therein, a carrier mounted to reciprocate within said casing, opposite doors pivoted to said carrier, and means. for raising said carrier within said casing.

7. The combination with a car having an inclined bottom, of a vertically disposed casing therein, a door forming a portion of said bottom and inclined diagonally to said casing, and means for raising said door into a vertical position Within said casing.

8. The combination with a car having an inclined bottom, of a casing therein, a pivoted door forming a portion of said bottom,

a device for raising. the pivot of said door into said casing, and means disposed beneath said bottom to engage the free edge of said door during its opening and closing movement.

9. The combination with a car having an inclined bottom, of a casing therein, a pivoted door forming a portion of said bottom, a slidingly mounted carrier within said easing upon which said door is pivoted, and a cross bar extending beneath said door to engage the free edge thereof.

10. The combination with a car having an inclined bottom, of a casing therein, a pivoted door forming a portion of said bottom, a device for raising the pivot of said door into said casing, a cross bar extending beneath said door to engage the free edge thereof. and a recessed bearing u on the edge of said door to contact with saic rod.

11. The combination with car having inclined bottoms. of a casing disposed cent ally therein, raising means traveling within said casing. opposite doors pivotally connected to said means, and means for securing said doors when lowered in closed condisposed tin the hopper portion, an elevating beam within said casing and hingedly connactcd to sald bottoms, means for shdably fin'oving said beam, and a rod for guiding said bottoms when opened and closed.

14. The combination with acar having oppositely inclined bottoms,"of an intermediate transverse casing, raising means traveling within said casing, and opposite hopper doors pivoted to said raising means and movable vertically into and out of said casing.

15. The combination of doors adapted to control a discharge opening, tracks for guiding the lower edges of said doors in ahorizontal plane, and means for guiding the n per edges of said doors in a plane at rig t angles to said horizontal plane.

1.6. The combination of doors adapted to control a discharge opening, means for guid-- per edges of said doors in a plane at a rightangle to said horizontal plane.

In testimony whereof I have hereunto aflixed my signature in the presence of two witnesses.
